Their song WAP made history becoming the first female rap collaboration to debut at No. 1 on the Billboard Hot 100, with the most first week streams and as the most streamed track of 2020. 
To celebrate, Cardi B gifted Megan Thee Stallion a custom Birkin bag painted with scenes from their steamy music video.

The Hot Girl Summer hitmaker, 25, shared videos and pictures of her new designer bag, thanking Cardi writing ‘thank you frennn (sic) omg I can’t believe you. I wonder what I’m gonna get her.’

The orange bag was designed on the front with a large white tiger surrounded by blue water drops.

To the right, a painting of Megan in her white tiger print bodysuit licks her finger.

It was inspired by the Texas-born rappers solo scene in their hit music video in a white tiger strip painted room with two of the animals.

Their video, directed by Colin Tilley and featured cameos from Kylie Jenner and Normani among others, also made history on Youtube, earning the biggest ever debut week for an all-female hip-hop collaboration, which has amassed 103M views as of Monday.

On the bag was a detailed streets and in a sunset pallet and ‘be someone’ read on a dividing wall.

While the sides of the bag were adorned with spray-paint inspired hearts and dollar signs.

Megan (born Megan Pete) videotaped herself unboxing the Birkin, which retails at its lowest for $9k without custom artwork.

‘My manager just walked in and said cardi sent you something,’ she wrote recounting the gift. ‘Not the birkinnnnnnnn.’

WAP marks Cardi’s (born Belcalis Marlenis Almánzar) fourth Billboard Hot 100 No. 1 after Girls Like You with Maroon 5 and I Like It with Bad Bunny and J Balvin both in 2018, and her solo track Bodak Yellow in 2017.

For Megan it is her second No. 1 on the chart ever and her second this year, following her Savage (Remix) with Beyonce in May.

They both celebrated their accomplishment earlier on Monday, with Cardi sharing a video of herself saying ‘My 4th number 1 on billboard hot 100. I’m just so thankful I want to hug the LORD!’

She added: ‘Thank you soo much @theestallion. I don’t even know how to thank you, I wish I can give you a big a** hug!’

‘Thank you to my fans Megan fans,’ she continued. ‘Thank you the world for listening. I’m just so thankful I can’t even type it. Imma get like a bad b***h and tell ya later. Love ya WAAAAAAAPP!’

WAP – short for Wet-A** P***y – has also been RIAA certified gold despite heavily sampling Frank Ski’s 1993 Baltimore club single Wh***s in This House.

The former stripper – who boasts 123.2M social media followers – triumphantly tweeted: ‘Power of the p***y!’

While Megan added ‘Me and cardi just got off the phone screaming. FIRST FEMALE RAP COLLABORATION IN HISTORY TO DEBUT AT NUMBER 1.’

She continued: ‘God is so great THANK YALL !!! @iamcardib thank you for all your words of encouragement, thank you for all the laughs, & thank you for having me on the record.’

Cardi continued to celebrate on Monday, sharing a photo of herself in a full Louis Vuitton outfit.

She wore a brown logo leather coat, with a matching beret and carried a small round handbag to compliment the look.

Despite soaring temperatures she wore ‘Yes it’s 94 degrees where I’m at. I’m still finna (sic) wear this jacket.’
